At a consultative visit, take a preoperative
full-mouth impression and bite registration. Send materials
to the laboratory for fabrication of stone models. Record
shade and provide to the surgeon for provisional crown order.
Pour models in die stone. Complete a diagnostic
wax-up for cases with three or more adjacent units.
Create a surgical guide using a duplicate model fabricated
from an impression of the diagnostic wax-up.

Immediately after implant placement, take a
localized index using the Fixture Mount/Transfers or attach
a transfer post. Apply heavy-bodied vinyl polysiloxane indexing
material around the transfer post with enough coverage to
ensure fixation. Material need not be applied all the way
to the implant engaging end of the transfer. Leaving access
to the screw holes apply additional indexing material to the
occlusal and incisal surfaces of two teeth on each side of
the implants. Minimal material is needed on the facial and
lingual surfaces as marginal detail was captured in the original
full-mouth impression.

Prior to retrofitting of the partially edentulous
study model, make a matrix of the edentulous area using silicone
laboratory putty.

Connect the Fixture Mount/Transfers or transfer
posts to corresponding implant replicas. Bore a hole in the
original, preoperative model to accommodate the replicas.
Fit the index with assembled transfers and replicas over the
corresponding teeth on the original model, ensuring passive
fit of index. Backfill the model with stone to secure the
replicas in place. Once the stone material has set remove
transfers and index from the adjusted stone model.

Trim the stone model to allow for the production
of a soft tissue model. Allow for at least 1mm of implant
analog to protrude above the stone surface. Occlude the top
of the implant analog with soft wax. Use the matrix of the
patient’s edentulous soft tissue area made in step 7
to create the profile of the soft tissue material.

At this point you have an accurate model
of the implant analogs, which can be used for fabrication
of the implant prosthetic. (UCLA abutments, cemented or screw
retained, custom abutments, prepping prefabricated abutments,
etc...)
